I'm too selfish to recommend you send it back "immediately". I want you to run it
through the paces first so we can hear the performance
reviews. Then you should send it back for a free replacement... imo.
This was a free original, so I don't think I feel cheeky enough to return it
It's getting a lot better. It's definitely loosened up a lot. It now presses every time when I do so normally, holding the
mod like a lighter and using my thumb to press the button. A few times I've tried holding it the other way around, so my thumb is supporting its back and I'm using one of my fingers to press the button - kind of like holding a flute, with my finger pressing a button instead of covering a hole in the flute. (I say as someone who has never held a flute.. )
Anyway, when I hold it 'reversed' like that, for some reason the button doesn't work quite often. I suppose I'm pressing it at a slightly different angle. The difference might be that when I hold it 'backwards', my finger presses down more on the top of the button - the higher end of the slope that the button is on. Where when I press it with my thumb from the front, the 'normal' way, it's more towards the bottom of the button/slope.
Anyway I don't plan on holding it that backwards way most of the time, and in practice it's not affecting me 99% of the time now, and maybe it will continue loosening until it's never a problem. I've still only had it less than a day.
The key thing is that no-one else has seen it. Therefore it seems unlikely to be a design or batch flaw. Just one of those things with mine.
